Abstract (en)

[origin: EP0296544A2] The invention relates to an immunometric determination method in which, in order to avoid non-specifically raised or lowered values for the antigen to be determined, a substance (suppressor substance) (6) is added to the unlabelled (1) and/or the labelled antibody (2) in excess, which substance, because of its great similarity to the reagent antibodies used and because of its great excess, selectively traps the substance (3) interfering with the antibodies and thus eliminates an effect on the assay. <IMAGE>
